Traversing all nodes in an XML file with VBScript

rob dixon picture rob dixon · Dec 15, 2009 · Viewed 27.4k times · Source

I have written a VBScript which is supposed to tranverse all nodes in an XML file, irrespective of the depth of the tree. This it does well except that the node names for the those nodes which are 2 or more levels deep are not displayed. I need the node names as well as the values so that I have name/value pairs for further processing by other programs. Can anyone please help me in getting the missing node names displayed.

Below is my code:

<html>
<head>
</head>
<body>

<script type="text/vbscript">
Set xmlDoc=CreateObject("Microsoft.XMLDOM")
xmlDoc.async="false"
xmlDoc.load("test.xml")
Dim objDocElem, strNode, strSubNode, xmlnn, xmlnv, xmlnc, xmldd, xmlfd, xmlfv

Set n_firstchild = xmldoc.documentElement.firstChild
Set p_node = n_firstchild.parentNode
Set pn_attribs = p_node.attributes
For Each pnAttr in pn_attribs
   xmlfd = xmlfd & pnAttr.name & chr(9)
   xmlfv = xmlfv & pnAttr.value & chr(9)
Next 

Set objDocElem=xmlDoc.documentElement

Set y = objDocElem.childNodes
i=0
Do While i < y.length 
If y(i).nodeType <> 3 Then
  If Isnull(y(i).childNodes(0).nodeValue) Then
     xmlnv = xmlnv & "Category" & chr(9)
  Else
     xmlnv = xmlnv & y(i).childNodes(0).nodeValue & chr(9)
  End If
  xmlnn = xmlnn & y(i).nodeName & chr(9)
  xmlnc = xmlnc + 1
  z=0
  Do While z < y(i).childNodes.length
    If y(i).childNodes(z).nodeType <> 3 Then
       xmlnc = xmlnc + 1
       xmlnn = xmlnn & y(i).childNodes(z).nodeName & chr(9)
       xmlnv = xmlnv & y(i).childNodes(z).text & chr(9)
    End If
    z=z+1
  Loop
End If
i=i+1  
Loop

document.write("form details: " & xmlfd & "<br />")
document.write("form values: " & xmlfv & "<br /><br />")
document.write("node names: " & xmlnn & "<br />")
document.write("node values: " & xmlnv & "<br />")
document.write("<br />node count: " & xmlnc & "<br />")

</script>
</body>
</html>

and the XML:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>

Please, try this:

set nodes = xmlDoc.selectNodes("//*")    
for i = 0 to nodes.length
    document.write(nodes(i).nodeName & " - " & nodes(i).text & "<br />")
next
